Sorry, I put my question into bad group. Can anyone move it to Net Express / Server Express group?

Thanks.

I don't believe there's any mechanism in Net Express to integrate with SCM mechanisms such as TFS.

Visual COBOL for Visual Studio integrates with TFS. Net Express (particularly version 3!) is now rather out of date; it was superseded by Visual COBOL five or six years ago.

Thanks for info, I think same, that connection from Net Express will be impossible. Please do you know if it's possible to use "old cobol" programs from Net Express in Visual Cobol, without any code changes?

In most cases yes. Some programs may need the (free) Compatibility Addpack.

Some programs may rely on erroneous or undocumented behavior which has changed. It's also possible that there are obscure features I'm not familiar with which are no longer supported. But generally it's simply a matter of recompiling.
